SPECIFICATION' forming part of Letters Patent No. 503,189, dated August15, 1893. I

Applica-tion filed March 1, 1893. Serial No. 464,188- (No model.)

T0 all whom t may concern.-

Be it known that I, FRANK C. ARMBRUSTER, a citizen of the United States,and a resident of Milwaukee, in the county of Milwaukee, and in theState of Wisconsin, have invented certain new and useful Improvements inWindoWs; and I do hereby declare that the following is a full, clear,and exact description thereof.

My invention relates to new and useful improvements in the constructionof windows, and consists in the matters hereinafter described andpointed out in the appended claim.

In the accompanying drawings illustrating my inventionz-Figure lis aninside elevation of a window constructed according to my invention andshowing parts of the casing broken away to better illustrate theconstruction. Fig. 2 is an enlarged vertical sectional view taken online 2-2 of Fig. l. Fig. 3 is an enlarged horizontal sectional viewtaken on line 3-3 of Fig. 1. Fig. 4 is a horizontal detail sectionalview taken on line 4-4 of Fig. 2.

Referring by letter to the drawings, A represents the Window casing andB B the upper and lower sash of the window. Vertically disposed strips BB are arranged to engage with the channels` or guides formed between thestripsE E at one side of the casing A, and the sash are hinged to thestrips B B as shown at l) b. Similarly disposed strips C C are arrangedto slide in the guide channels at the opposite side of the casing andare arranged to be detachably engaged with the sash. The usual weightcords D D are 'engaged with thesestrips B C, instead of being directlyengaged with the sash, so that when the sash are secured to the saidstrips, the weights will serve to sust-ain the sash in any adjustedposition in the usual manner.

In the strips C, I provide suitable studs G G, arranged to projectthrough apertures in the stiles of the sash as shown more particularlyin Fig. 3, and having screw-threaded ends g g, with which suitable nutsg g may be engaged to hold the sashv to said strips. I also provideapertures e e in the lower ends of the guide strips E E as shown andsimilar apertures c in the vertically disposed sliding Strips B B and CC, and provide pins F which may be slipped through said apertures e eand into the apertures c c when the sash has been moved into a positionto bring said apertures into register, and I arrange said apertures cY cat a point in the stiles of the sash which will cause the lower edge ofthe sash to come above the line of the sill, when the said apertures c cand c e are in register. When said pins F F are in engagement with thestrips B and C, the said strips will obviously be held from verticalmovement.

Any suitable device, such as the pull I is let into the face of eachsash, and affords means for swinging the said sash upon its hinges in anobvious manner.

When it is desired to swing the sash upon its hinges for cleaning orother purposes, it is only necessary to adjust it so as to bring theapertures c c and e e into register and insert the pins F as described,and then to remove the nuts g g when the sash is free to swing upon thehinges. This greatly facilitates the operation of washing windows asboth surfaces of the glass are thus made readily accessible from theinside of the room.

In order to permit the upper sash to be swung inwardly as described, Iiind that it is necessary to provide means whereby the lower sash may beelevated so as to bring its upper rail somewhat above the top of theWindow opening so as to allow for the thickness of the sill, and for thethickness of the meeting rails of the two sash, and to this end Iarrange a vertically movable cross piece H above the top of the groovesor guides in which the lower sash Vmoves which has suitable projectingtongues h h engaging with grooves h h at the top of the casing. When thelower sash is raised, it will engage with this cross piece, and elevateit in an obvious manner, so as to leave plenty of room for the uppersash to be moved down and swung inwardly upon its hinges below the lowersash. The pins F are at such times pressed through the strips E E andinto engagement with the strips connected with ,the upper sash in themanner before described, and the nuts g g being removed, the sash maythen be freely swung inward.

It may be desirable at times, to entirely reA move the sash for thepurpose of reglazing, and for this purpose, I prefer to employ loose IOOpin butt hinges, the pins of which maybe removed in a familiar manner,to free the sash from the strips B B.

Having thus described my invention, what 5 I claim as new, and desire tosecure by Letters Patent, is

The combination with the easing and the sash of a window, of verticallydisposed strips engaged with opposite sides of said casing, a

ro hinged connection between one of said strips and one stile of thesash, screw-threaded pins in the other strip, apertures in the otherstile ofthe sash for the reception of said pins, and nuts for detachablyholding said latter strip in engagement with the said stile,substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of Wiscousin, in thepresence of two Witnesses.
